Close Session Forced

[tiroso]

Hello again in this repo, Everytime I try to find an element, which is not there, my session will automatically closed. I cant find the parameter for just warning and not destroying my session.

That sounds pretty bad. Is a die() being thrown, or is it warning and whacking the session somehow?

Here is the die message

SubProcess: onRun returned error: Not Found :

There is no error message if the button is located on the site... I can handle it with eval{} but i think thats not an elegant solution.

Working:

eval{
   $session->FindElement( using => 'css selector', value => '#onetrust-accept-btn-handler' )->ElementClick();
};

Not working (throws error and process died) (but is working when the Element is found:

if (my $element = $session->FindElement( using => 'css selector', value => '#onetrust-accept-btn-handler' )){
   Log3 undef, 1, "Found Accept Button";
}else{
   Log3 undef, 1, "Didn't Found Accept Button";
}

In your other repo i have to call the function "find_element_by_css" to throw just a warning and not to kill and destroy the session. Maybe i've just not read the hint for Selenium::Client

Ahh. So it's just dying. Some people like the sort of "klingon programming" paradigm (better to die() than return() in failure), so I think I should make this behavior controllable via a switch passed on instantiation.

I'll implement this feature later this week.
